I would hope so, otherwise he has a lot of joints for nothing, given the arm mode is more or less just the vehicle mode with the treads folded into his lower arm. If you look at where the guy is holding him, you can see what looks like "Scavenger's" shoulder, mid-bicep rotation and elbow joints.

EDIT: Looks like it uses the same socket and plug system from the Energon/Universe combiner teams.
