This answer isn't entirely consistent with the rules. It is true you cannot off units along the way the act of landing troops / PDS / leaders can only take place in the activated destination system during a tactical action. However, you may pick up GF from unactivated systems en route to the destination, and land them upon arrival.
That is true. Given that all systems the carrier passes through must be passed through in the Movement step, however, I don't see any inconsistency between this and my answer. It's a good thing to keep in mind, though. Being able to pick up GFs en route is definitely important.
