No, Steamboat Mickey does. That's the Mickey from the very first movie in the 20's. The current Mickey can't be used in any format. The book Winnie The Pooh is already available but not Disney's version of Winnie The Pooh. Don't mix them up because Disney can and will come after you. They have been known to do it, and they are really harsh about using their copyrighted property. They will run you out of business just to prove a point.
"Current artists and creators will be able to make use of Mickey, but with major limits. It is only the more mischievous, rat-like, non-speaking boat captain in “Steamboat Willie” that has become public.
“More modern versions of Mickey will remain unaffected by the expiration of the Steamboat Willie copyright"
