It is possible to kite certain bosses around the map.
Ragnarok and Omega can be kited all over the place. I'm not sure about Vielle and Masterius, though, since they're such a rare spawn. And the fact that they're going to be surrounded by asmodians / elyos who are protecting them and pvping those who come to kill them.
Fort Bosses, however, can be kited around inside the fort and this is the greatest visual example ever:
