Yes, but you realize that isn't the same as publicly stating you directly took Disney material and trained a commercial AI on it and are selling use of it for profit, right?
Disney is within its rights to choose not to pursue fan art or small snippets of their work. Having been lenient on it for a couple of decades means it becomes hard for them to prove that what you trained on was actual Disney content, or fan-art. The provenance is unclear, making suit difficult.
But, if this really is absolutely clearly not copyright violation, then there should be absolutely no problem being up front about using authentic Disney content. "We took official, commercial copies of these elements of the Disney catalog, and trained an AI on them," should be a selling point.
Folks should be willing to invest major portions of their life savings in the Disney-trained AI. If there's no copyright issue, there's little risk. It'll make a mint!
