Yep, the rotor can be removed with the rear caliper in place. Quite slick as a matter of fact. Then the piston can be accessed for pushing & turning (buy a tool for this purpose or be careful and use a pair of needle nose pliers as a spanner of sorts). All that needs to be removed for the procedure, besides the pads, is the retaining pin (drive it out from the inboard side). Did I mention this is a pretty slick setup.
Make sure your replacement pads are thin enough (I think the stock pad material thickness, not including backing plates, is 6mm, although I think you could get away with almost 8mm). With a mostly new (standard width) rotor, there are pads that are too thick (like some hawks and I've seen others mentioned here). Apparantly, the pad shape is some stock viper part, but ours need to be thinner to start with.
FWIW: Including the backing plates, new Hawk HPS front are 14mm and rears are 14.8mm (and these, per the above, are too thick I might add).
