No, he didn't . All people need to do is read and comprehend the manga to understand that.
When Luffy stated he figured out how to used ACoC (infuse things with CoC) Kaido laughed at him stating it's a power only a handful of the strongest can use. It's not a power a dead man walking can use.
When Zoro used his Asura mode technique we got a very different reaction from Kaido. He didn't say anything about Zoro infusing his attacks with ACoC or how that should be impossible for someone with a foot in the grave.
Instead, his statement was almost identical to when Luffy used CoC at the beginning of Wano.
