Can I use my trail GPS watch for road running too?

Absolutely. Trail GPS watches do everything road watches do plus more. The only trade-off is they tend to be larger and heavier. If you only run roads, a lighter watch like the Garmin Forerunner 265 is more comfortable.

Do I need maps on my GPS watch?

For trail running, yes. Unlike road running where you can follow sidewalks and intersections, trails fork unpredictably. Onboard topo maps let you verify you are on the correct trail and navigate back if you miss a turn. They are essential for backcountry runs.
