I will have to say no just to be on the safe side. In this case, if the fare has been cheaper, the schedule change is a reason for full refund

I would cancel the ticket, get the refund, and book it as a new ticket.
(Note - I would say you should not book the new ticket unless you have submitted the refund request.)
