Black Zetsu later controls Juubi Jinchuriki Rinne Sharingan Dual rinnegan madara. So clearly, BZ is strong enough to control juubito,

Obviously to not arouse any suspicion he can't really do that, he must remain pretending to be madara's will.

As to madara, with Rinnegan he could for example pull out Obito's soul. Though if he wanted he could've had White Zetsu get the second rinnegan, implant it into, say, Kakashi, then use his power to force him to use Rinne Tensei.
