I did almost exactally that with mine. I used 2" pvc instead of abs. I honestly don't remember how I hooked it up to the outlets. I think I was able to force the oddball pipe into the pvc, but I wouldn't swear to it.Just experiment if you haven't a;ready and find out the best way to adapt the two together. Larry
There is special thin-walled plastic tubing intended for central vacs. The advantage is that it's flexible enough to make it around some obstacles without a fitting, which is where clogs happen and which also reduce suction. It's also cheaper than PVS or ABS.

Thin-walled central vac tubing was a little cheaper than ABS drain pipe when I last bought it. See what you can find online.
Even so, I think it's false economy. The plastic pipe intended for cental vacs is more flexible so it's easier to install, it's smoother internally to reduce clogging, it's lighter so there are fewer problems with bracing vertical sections and the termination fittings you'll be using are probably intended for thin-walled pipe.
I've done two whole-house vac installs. Believe me, you're in store for enough aggravation trying to thread pipe around electrical boxes and all the junk that's inside a typical wall. You'll appreciate the extra expense if only for its "bendiness".

Is there any reason not to use 2" abs for a central vac setup. It is cheaper and slightly larger than the proper pvc pipe and there are many more fittings available.

The only problem I see is connecting the pipe to the outlets. You are going to have to find some kind of bushing/reducer/coupling.
I DO see your point though. Why DON'T they make it a standard size?
That is the point of my question, locally the special thin walled tubing is more expensive than standard ABS.
