Disney has options even if copyright legislation doesn’t change. For over a decade now, Disney has used clips of Steamboat Willie in their logo. Even after Willie’s copyright indisputably expires in 2024, they may attempt to litigate under trademark law.

That kind of thing doesn’t always work though. For example, Lego has repeatedly attempted to trademark their brick shape in various venues after the patents expired. Their many resulting lawsuits against Mega Bloks have (to my knowledge) been generally unsuccessful, because the functional elements of an interlocking brick design turn out not to be trademarkable.
