Nothing wrong with that.  You don't want to cause an error if <TAG> is
not found, so it's better to say:

 (search-forward "<TAG>" nil t)

and you don't want to delete any characters if <TAG> is not found, so
make it conditional:

 (when (search-forward "<TAG>" nil t)
       (backward-delete-char (length "<TAG>")))

Finally, why not add this to c++-mode-hook, by putting the following in
your ~/.emacs init file:

 (add-hook 'c++-mode-hook
           (lambda ()
             (when (search-forward "<TAG>" nil t)
               (backward-delete-char (length "<TAG>")))))

This tag search will now be performed every time a buffer enters
c++-mode.

You can ensure a file always enters a certain mode by specifying the
mode in the first line, like so:

# -*- mode: c++ -*-
#
# ~/c++/test.c
#
<TAG>



Good luck.
