Probably not. Its more likely that Boba still has Slave 1 in the new TFA canon, because it is iconic and looks better.
I personaly never liked the idea of Boba giving up Slave 1.
do we even know if The Fett is alive in the new canon ?
If you read Aftermath (which IS canon), it does not appear as if Fett survived ROTJ. What appears to be his armor shows up in a scene that takes place in a Jawa sandcrawler.
