The short answer is no. But the possibility of it being an item obtained through trade: a weak maybe.

Curved blades or the saber in Europe have often been associated with the East meaning the Huns (curved swords being called in medieval European writings as gladius hunnicus or "Hun sword") and the Turkic tribes. The purpose for a curved sword is they are made to make slashing cuts more effective since the swing of the arm and blade makes the edge cut more efficiently than a straight sword. We know that the steppe tribes were known for light cavalry riding into battle on horseback shooting arrows and quick melee attacks so they can run away after a strike. Since stabbing a foe may mean slowing you down or loosing the weapon in the impaled foe, slashing is your best bet. As sabers are designed for slashing and even for slashing on horseback the weapon is very much tied to being a cavalry type weapon in Europe.

Vikings when they fought, like most of the other Germanic tribes, fought on foot behind shield walls. This tendency continued until the Battle of Hastings which marked the end of the Viking Age. The reason for this is not entirely known (although there are guesses) but it meant that all weapons had a function for breaking the opponents shield-wall and one-on-one combat. With a straight sword you don't want to slash at shields because the blade could get caught in the shield opening up an opportunity for your opponent to disable your weapon hand/arm. Thus blades were straight and pointed to allow for stabbing between cracks in the shield-wall (swords were actually pretty uncommon on the battlefield with your typical foot soldier using a spear or a hand-axe). A saber in this case would be largely ineffective. On top of that, chain-mail is not very good with protecting against concussive blows and stabbing by spears but are excellent against cuts and slashes meaning sabers would be ineffective against most chain-mail.

The Magyars of modern day Hungary were horsemen from the steppes that began settling around the area in the 9th-10th century, right in the middle of the Viking Age. There are burials that have sabers, so the sword design existed during the period. These swords could even be found among tribes that were in Russia that lived along the Volga as well as in the Middle East. These are all areas Viking explorers have traversed and traded in thus it was a weapon that they came across. That said, if it was something they would have used, there would have been one burial that had a saber but alas I have not seen or heard of any. Thus a Viking owning such a blade is doubtful especially since the way they fought wouldn't make the saber as useful of a weapon.

Now the Vikings may not of had curved blades but there was a style of sword that only had one cutting edge that was popular in Norway. The sword is thought to be a mix between a seax (particularly a langseax, which is a big knife popular from the Migration period to the end of the Viking Age) and a double-sided straight sword. The advantage to such a sword is that only one edge needs to be sharpened and they probably were easier to make since a fuller was not pounded in to make the blade lighter and the sword doesn't need much effort in regards to balancing.
