I don't believe so. It's ACC that unlocks the Callisto to Deneb, and the Jetway doesn't look like it has it. Here's a list to the known boards that can/will unlock them, but personally, I wouldn't do it except for funsies. Those cores are disabled for a reason usually, mostly because of bad cores. I would imagine if AMD needs some Callistos really fast they would rebrand Denebs, but probably not too often.
