If they're going after a particular version (such as the Disney movies) then they're fair game. Straight fairy tales have so many different versions that it's hard to judge what's canon and what's not, so I think we mostly avoid them.
Bad Slash and such involving canon fairy tale characters could probably be PPCed, if the violations are obvious.
