The Uchiha can still use Izanagi without Senju power, but it will be limited compared to Izanagi with Hashi cells. And to put Obito's statement in context, he meant that only those who have effective control of both the Uchiha and Senju powers can use a powerful version of Izanagi. He said that Danzo lacked effective control of both the Sharingan and the Hashi cells, so his Izanagi was severely limited to about one minute. Whereas Obito, a true-born Uchiha with much better control over Hashi cells, could extend Izanagi to at least 5 minutes.
