Definitely. Oden's spirit pretty much imbued conquerors haki into his other swords. Zoro doesn't have conquerors
Kaido said the haki is strange.
Strange -
not previously visited, seen, or encountered; unfamiliar or alien.
Let me make sure I understand everyone. People believe Oden's haki was stored in enma and used by Zoro even though:
- Emeth had to use a technique to release the haki
- Zoro didn't use any summoning haki jitsu
- Oden never showed or hinted he knows the summoning haki jitsu
- Kaido is familiar with Oden's haki, yet wasn't familiar with the haki coating enma
- Kaido is not familiar with Zoro's haki
- Kaido said Zoro has CoC haki
- Fodders passed out from Zoro realized he must use his overwhelming haki to master enma
