If he transforms, he could get too violent and make a mistake while fighting with the Kanima. Besides, Derek has been a Beta for so long that he's probably just used to the partial transformatio.Then there's also the fact that he likes to be in control of himself, instead of transforming and becoming more animalistic.

Then again, him not being able to transform fully may tie in to the theory that Peter Hale may stilll be alive, albeit just barely.
