I don't think so. All AWD automobiles have instructions on the manual about proper tires to use. Even some ATV's require the right set of tires for the front and for the back. The tires for AWD vehicles should match each other in accordance to the automobile manufacturer's instructions in the manual, since the vehicle's traction control responds to what is happening to each tire in relation to traction.
There is a lot of information in here:

Now, for FWD vehicles pairs of tires can be replaced. In this case, the new set of tires should be installed on the rear, and the partially worn tires in the front.
