I think this debunks these rumors. MARVEL released their press release on the official casting of Aaron-Taylor Johnson and Elizabeth Olsen as referring them as QUICKSILVER and SCARLET WITCH, They state it several times in the press release, so it's safe to say that the rights issue has only pertained to them being called mutants or being related to Magneto.

Here's the official quote:

OFFICIAL: Elizabeth Olsen & Aaron Taylor-Johnson Join as Scarlet Witch & Quicksilver !

Aaron Taylor-Johnson and Elizabeth Olsen have officially joined the Avengers family as the brother-sister duo of Quicksilver  and Scarlet Witch in Marvel's "Avengers: Age of Ultron,"

It also should be noted that they do not refer them as Pietro and Wanda Maximoff.
