(Well you technically are the leader, but you aren't the Grandmaster until you do Under New Management, which requires you to do the four city quests and the khajiit caravan quest, which all have their own requirements. But yeah if he wants he can still join the guild, though there won't be any main quests for him to do and it will restrict him from joining any other guild.)
