Hmm, I don't see why. Try this:

    (defun ignore-edge-of-buffer-errors (default-fun error context signaller)
      (unless (memq (car error) '(beginning-of-buffer end-of-buffer))
        (funcall default-fun error context signaller)))
    (add-function :around command-error-function
                  #'ignore-edge-of-buffer-errors)
