Which is to say Disney stopped the theatre from showing the movie. The reason the theatre couldn't show the movie is because Disney wouldn't allow it to do so.

No, theaters can't just use any copy of a film to show a movie; those copies are jealously guarded by the distributors and are subject to strict controls, especially by Disney (and Fox too, before the acquisition). Generally, each copy of a film reel must be acquired from the distribution company and returned to it after the theater's second-run showings have ended. (For digital projectors, they use an online check-in/check-out system.)

Disney never gave the theater the film (or file, depending on the theater's projection setup) in the first place. The theater could not have shown the movie without affirmative action on Disney's part.

Disney could have simply done nothing at all, and the theater would not have been able to show the film.

I don't think you understand the meaning of "can". It's not a legal term. The use also occludes the active role Disney and other license holders play in the prevention of screening movies.
