Everything is canon. :D No, seriously, that's the premise of the Tardis Wikia: everything is valid to some extent.
Obviously DWU: Exile takes place in a weird side universe, but that doesn't mean its physical laws are invalid. (Also it amuses me that it's yet another story with 'future Doctor actor plays a Time Lord who beats up the Doctor' - hi, Colin Baker!)
But yes. I've only listened to the Unbound stories once each, so while I recommend the concept, I can't really comment on the quality. And no, it's absolutely not something that's going to be held up/looked to as canon.
(In fact, Unbound has already been explicitly made uncanon at least once - the one where the Doctor gets shot immediately after regenerating, and thus regenerates again. Um, no - depending on how it's done, that would either cause the regeneration to fail, or cause a River Song-esque light show. It certainly wouldn't cause a second regeneration.)
But it's still an amusing idea. And maybe Time Lord Tennant is just... not a very nice person? (In fact... pretty sure he isn't, thinking about that story.)
