IMHO, not quite, drive your car at ALL speeds in 4th gear and see how long the
engine lasts (don't down shift on corners, accelerate from 20 mph to 60 mph in
forth, etc). Sure the engine is turning slow, but you are putting other
stresses on it. Look out bearings.
This may be the extreme but it illustrates rpm isn't the only determination of
wear.
Remember the movement of the piston in the cylinder is just one function of wear
and is probably a minor player. The effort needed to push the piston down has a
greater effect on wear than the rpm of the engine. Of course a constant 6000
rpm will shorten an engines life, but the difference between 4000 rpm and 3280
while cruising down the highway is probably offset by the effort needed to move
the engine at the lower rpm.
