Yes, absolutely. The Constitutional Convention of 1787 was held at Philadelphia, and it's sometimes called by either name.

Incidentally, the constitution produced in the Convention of 1787 (the same one still in force) is sometimes called the Constitution of 1789, because it took a year for the states to ratify, and until the spring of 1789 for arrangements to be made, electors to be appointed, and the new government to come into place.
