Yes, but not the way people think. Haki in One Piece is a synonym for spirit/will/ambition. When Blackbeard met Luffy first, he could gauge his strength feeling his "Haki", while in Impel Down saying that Luffy's Haki became stronger too. That was, when Luffy couldn't even use Haki (only conqueror's Haki subconsciously). Law said, he could not move Big Mom and Kaido due to their strong Haki, which was not armament however, but their overall Haki/spirit strength.
It's the same with Enma. Oden's will/ambition resides within Enma and Kaido can sense it. But it doesn't do the job for Zoro. He imbues it with his own armament and CoC.
