Owned a few AWD and 4WD vehicles and understand the engineering behind them. I would think that if an XC70 has the Haldex system, it could be towed with the rear wheels on the road provided that the car was not on since it's the Haldex unit which determines engagement. Regardless, I think one should be able to tow it if I remove the driveshaft.
