Nearly any 4X4 vehicle with a NEUTRAL position in the transfer case can be towed four down.
I say "nearly" because there are ALWAYS exceptions, and somebody is bound to point one out if I don't say "nearly" or "almost" or some other such qualifier.
there may be 4X2 vehicles with automatic transmission that can be towed four down, I don't know.
It pays to read the Owners Manual and follow the instructions contained therein. The book may not always be correct, but the dealer doesn't have much of a leg to stand on in denying a warranty claim if the instructions were followed to the letter and something goes wrong.
