You absolutely can remove those parts with minimal effort.
You can also make yourself a decent chunk of change selling them. The trunk is pretty universal to most any trunk mount, and the saddlebags can be swapped to at least a Roadstar.
The trunk would fetch $300-$500+ depending on condition and year, and the hard bags would pull $200-300 without much problem if they're in good shape.
I know I'd be interested if the price was right. Are you looking at a used bike and wishing it wasn't a bagger?
