No, The Silent King had the complete and utter servitude of the Necrons via command protocols which the C'tan gave him.
Could there be a Tomb World or even Dynasty still loyal to the life-consuming legacy of the C'Tan?
I don't see why not (and besides, there are the Destroyers, but they want to eradicate all life instead of turning the galaxy into a giant cattle ranch like the C'tan wanted).
