No, cultists are normal imperial citizens who have joined a chaos cult or a citizen of the eye of terror who has joined with a chaos warband.

A renegade guardsman is a former Imperial guardsman, Imperial mercenary, or PDF soldier who turned their back on the Imperium to join the forces of chaos, the difference between the two lie in their origins.

I know what youre' thinking though "Damn, I wish Dawn of War had renegade guardsmen" that's why I play it with mods :D
