I have a portable Air Conditioning unit and would like to use the
chimney as an exhaust, can I just put the extension hose into the
chimney and let the hot air rise out like a fire would ?. It would
seem better than using a window as that worked but very hard to make
it in anyway airtight.

Most aircons generate not just hot air, but hot very wet air, to the
point where a lot pf it drips around the place..if the tube goes
straight up, chances are it will run back down the tube into the unit.

Of course that depends a lot on the exact unit, which is unspecified.

I'd say it produces nothing like enough heat to create an updraught.

Don't forget that its fan driven at a fair speed.
It would suck all the remaining cool air up the chimney and remove the
effect of the AC pretty quickly unless the hose is sealed to the chimney to
stop it drawing the room air up the chimney IMO.
