Good observation, Aquatain. It's quite a distance from the Emperor's throne room tower at north pole to the (at least 636.4km, in a straight line) equatorial docking bays.
You're probably right, too, about the Emperor probably having some sort of private transit system from one to the other, so Luke would only have run into troops before entering the system and after exiting it. By the time he was exiting the hangar end, from what we see, apparently the damage to the station had reached the point where the troops were too disorganized to offer any resistance.

Ah, I see.. but still, he would need it to defend himself from possible resistance from Imperial troops on the station.
Not only that, it simply wouldn't be logical to leave behind his lightsaber when he could so easily pick it up (with or without TK.. let's not speculate about such mundane details). Don't forget that Jedi have more of a connection to their personal weapon than most folks do.
