Not without editing the module, no. Joomlas permissions are designed as such, sorry. It's probably more accomplish-able with Joomla 1.6 and its more advanced permissions system. Within the module if you choose to edit it you'd simply need to put an IF surrounding it and checking for "isModerator( USER_ID )" this function (JUST AN EXAMPLE!) would check if a user is a CB moderator or not.
