Q. My Vigor router is Annex A, can I use it on an Annex B line? If not, is there a firmware available for upgrading the Annex type ?

Sorry that you can NOT apply an Annex A router on the Annex B line, and vice versa. Since they are totally different in hardware, of course a firmware upgrade cannot change the Annex type.
