Yes: in a universe in which the expression we know as "2" instead meant the quantity that would be known as "2.5" in our universe. That is a universe in which the expression "2+2=5" would be mathematically correct.
Now, if you're asking whether a pair of objects and another pair of objects lumped together would make five objects, then no, but then, in that case we're talking about concrete physical objects and not the numerical label added to them for ease of communication. You aren't talking about "metaphysical necessities" above, Steve: you're talking about conceptual properties that are dependent on minds to exist. The number two doesn't exist as some objective state, through which our number two is derived; two is a conceptual label we give to a specific set in order to better quantify the universe.
