No....
The thing is, is that simply being able to damage Kaido, isn't enough to solidify anyone as a YC caliber character. We know Duke, Neko, Ashura, and Denjiro for sure are hovering around low high tier.
And I mean, Kaido is still the most naturally durable character in the series. We still haven't seen what happens when he mixes armament haki with his Dragon scales, which I am sure that's what Oda is saving for Luffy to get past.
