A cleaner approach would be to send CANCEL first for the re-INVITE transaction and then a BYE to terminate the dialog.

If you want to terminate the entire call, then I think you can send a
BYE. If you want to terminate the reinvite and thus reinstate the call
as it was before the reinvite, then you must send a CANCEL.
AFAIK, you can send a BYE within the dialog any time after the initial
ACK has been sent.
