Since when does Bryan Singer call superheroes by their superhero names? He even made fun of it with Logan's dialogue in X1. Even if Fox are the only ones legally able to use "Scarlet Witch" and "Quicksilver," he'll never call them that. Just "Magneto's Daughter" and "Magneto's Son" in the credits, if that much.
And I fail to see the semantics of calling them something besides "mutants." Their power source was non-genetic from 1962 through the 1980s (it was the convoluted Wundagore saga that explained it), so Marvel Studios has plenty of "authentic" ways to explain their powers besides the X-gene.
