Just as we have the genesis block which is block 0, is there a special name for the block currently at the head of the chain? Obviously such a block would be observer dependent and never absolute but I am curious all the same.


The Bitcoin source code refers to it as the 'tip,' e.g., UpdateTip, SetTip, ConnectTip. It's sometimes referred to as the latest block; that's not totally accurate, since the latest block is not always the tip.

Nothing formal, but "latest block" pretty much describes it.
