Hm, I don't know why, but I confirmed w3m renders at least
    <a href="z"></a>
as: <a href="z"> </a>

I see.  Could you test this hook with such html contents?

--8<---------------cut here---------------start------------->8---
(defun my-w3m-remove-hidden-anchors ()
  "Remove hidden anchors like \"<a href=url></a>\" in the current buffer."
  (goto-char (point-min))
  (let ((case-fold-search t))
    (while (re-search-forward "<a[\t\n ]+[^>]+>[\t\n ]*</a>" nil t)
      (delete-region (match-beginning 0) (match-end 0)))))

(add-hook 'w3m-fontify-before-hook 'my-w3m-remove-hidden-anchors)
--8<---------------cut here---------------end--------------->8---

If it is ok, I'll embed the identical thing into emacs-w3m.
