Sorry, I should have said: add it to org-export-before-processing-hook,
so you use it like this:

#+begin_src emacs-lisp
(defun my-export-delete-headlines-tagged-noheading (backend)
  (dolist (hl (nreverse (org-element-map (org-element-parse-buffer 'headline)
                                         'headline
                                         'identity)))
    (when (member "noheading" (org-element-property :tags hl))
      (goto-char (org-element-property :begin hl))
      (delete-region (point) (progn (forward-line) (point))))))

(add-to-list 'org-export-before-processing-hook
             'my-export-delete-headlines-tagged-noheading)
#+end_src
