I'd want to say "no" to that, but Kaido's ACoC attacks haven't been greatest stuff so far.
-Law no sold it. Took very little damage from a CoC coated TB from Hybrid Kaido. Fell for a bit before going to fight BM all dandy.
-Base Luffy matches some swings
-Yamato matched some swings
-Even already half dead Kinemon managed to take one directly to the head and still not only be conscious enough, but also moving
Kaido's general swings aren't really that grand. I don't find it hard to believe Zoro will be able to block quite a few, and retaliate somewhat similar to Yamato. Ofc, he will be send flying if Kaido uses one of his stronger attacks.
Also, scarring aspect DID leave Kaido jaded, visibly shaken and huffing on top of coughing blood during that scene. Ofc it didn't leave him crumpled, but so far it has done more visible damage than anything else done to Kaido, which is saying a lot, as Kaido has tanked a lot of hits. Luffy will eventually deal more damage, but scarring someone permanently for life is great AP feat.
