The Rules of Golf have strict definitions of what does and doesn't count as a golf club. A pool cue doesn't have a face, therefore it doesn't count as a golf club. You should be allowed to carry it in your bag without it counting as one of your 14 clubs, but you wouldn't be allowed to use it for golf.
In accordance with the rules, you are only allowed 14 clubs for a stipulated round of golf. This is only for official rounds of golf, if you are just playing a casual round of golf you can carry as many as you want.
