I’m building an Island in the middle of my shop that will house my table saw, chop saw, and router table. Underneath the Island I’m running 4″ PVC duct work…My questions are: Should I cement the fittings together (45s, 90s couplings, etc)? Or should I leave them loose in case of a clog? How do you remove clogs? If I cement the fittings together, can’t you use a plumbers snake to remove? What do you suggest?

Personnally, I would not cement them. If you start having problems with them comming apart, then you can make a couple of cuts down into the flange of female side of the connections and use a band clamp to tighten it down onto the male side. At least this way its not permanent and you can move it without having to replace a lot of it.
As for cleaning, you wouldn't want to use a steel snake on it because it will scar and nic creating a new place for something to hang up. A garden hose with a taped up male fitting and lp air works pretty good for clearing up clogs on long runs. It doesnt take much air to blow it out just remember to blow it back the opposite way it went in.
I don't know what your budget is like but if you can afford the clear plastic pipe and fittings that is the ultimate way to go. Not having to guess where the clog might be is a pretty nice advantage. It is pretty expensive and most would probably consider it extravegant.

Leave them loose. Duct tape if needed.

id leave them loose, however in lieu of duct tape get the tape contractors use to seal up tyvek or house wrap (basically its polyethelyene tape red in color under the 3M label). Its a bit sturdier as far as adhesive longevity and wont become brittle and lose its outer layer like the attractive duct tape can.
