An alternative to using the :noexport: tag, and also to
the other suggestions given here in this thread would
be to use `org-map-entries' to physically remove all
subtrees which match your condition.  You can call the
mapper from one of the preprocessing hooks:

(defun my-export-remove-TODO ()
  (org-map-entries
   ;; The following form will be evaluated at each matching tree
   '(progn
      (outline-mark-subtree)          ; mark tree
      (delete-region (point) (mark))) ; remove it
   ;; Now the tags/property/todo matcher to select trees
   "LEVEL<15+TODO={.}"
   ))

;; Call this after other tree selection has been processed
(add-hook 'org-export-preprocess-after-tree-selection-hook
	  'my-export-remove-TODO)

The matcher includes a LEVEL<15 test to make sure this will
not mess with inline tasks.

Export preprocessor hooks are a good place for such tasks.
Also Nick's proposal could be used in such a hook, but not
the same hook as I have used above.  Maybe in
org-export-preprocessor-after-include-files-hook.

Nick, an easy way to set a particular tag is

(org-toggle-tag "noexport" 'on)

The line number stuff  in org-change-tag-in-region is there
to allow people to have point in the line *after* the last
headline to change.  But maybe you can fix this by making
a special case for point and mark in the same line...
