Not necessarily, Oz_P, the fuselage can be shorter if the tailplane is mounted on a swept fin which extends the moment arm. Have a look at the plan view of any of the aircraft mentiond. This also reduces wetted area and therefore drag. I would also expect that the designer gets more freedom to shape the back end the way he wants it.

Rear engine aircraft probably have high tails by necessity, and high wing A/C also e.g. 146, C-141 and Galaxy, the former structural and the latter aerodynamic.

It has also been said that the tailplane provides an endplate (winglet to regie spotters ) effect to the fin, improving efficiency of that surface and the rudder as well.

The Beech 200 may perhaps illustrate the advantages in that it seems to have a minute tailplane mounted well aft.
