You cannot upload the journal’s version, but you can upload the text as accepted (so, the same content minus the formatting).
I suspect that any editorial changes that happened as part of the journal's acceptance process - unless they materially changed the content - would also have to be kept back as they would be part of the presentation of the paper (protected by copyright) rather than the facts of the research.
