As far as I can tell, The Disney versions can be trademarked, but other different versions of Mickey could be produced by other people. The best example I could think of from the top of my head was the original 'Three Stooges' films of the 40s and 50s differing from the 70s Hanna-Barbera "Three Stooges" cartoons. Another example would be the various film versions of "The War of the Worlds" and then the Musical version from the 70s. All different, but all using the same scenario.
