Not your op but I personally do not. The way the word has evolved blockchain includes the distributed consensus. I understand there is a concept of linked blocks, into a chain, and technically Bitcoin and folk are those. If someone said blockchain (datastructure) I would understand it as being only the data structure.

git is a chain of blocks, kinda. it's distributed. there is no consensus. It's not a blockchain by how most people would define it.
