I've opted for the solution proposed by Sylvain (test that the file exists):

#+begin_src emacs-lisp
        (add-hook 'before-save-hook
                  '(lambda ()
                     (when (eq major-mode 'org-mode)
                       (org-align-all-tags)
                       (org-update-all-dblocks)
                       (org-table-iterate-buffer-tables)
                       (when (file-exists-p (buffer-file-name (current-buffer)))
                         (my/org-remove-redundant-tags))
                       )))
#+end_src

Redundant tags is something I won't do as soon as I create a file for the
first time. Hence, I consider this as really "good enough", even if not
perfect.

Thanks for your help!

Best regards,
