Fine on the D2. The torsen centre diff will happily deal with the front or rear axle spinning independently for a short period of time. I have mine tested on the rollers with no adverse effects or unpleasant noises.
Not so much with Haldex things, as if the clutch in the rear diff is engaged and you spin the rear wheels with the front stationary, bad things happen.
Stuff with permanent 4wd and no centre diff like a Landrover would just drive itself off the rollers.
