1954, actually. But it's a minor thing. You don't need to know anything about the IBM 704 to write Lisp. A cons cell is a specific data structure and its components have specific, if unusual names. There's a lot of unintuitively named symbols in Lisp that are better targets for criticism than car and cdr.
Linked lists are comically inefficient on modern hardware and naming two of your fundamental operations based on CPU instructions from a chip from the 60s is not what I would call good API design.
