No, you should be able to ride it on some simple trails but nothing too rough or steep, it wouldn't be a good idea to ride it too fast and don't take any jumps on it unless you want to end up in hospital.
I'd only ride that bike on a dirt road.
That bike probably has or had a sticker on it like
this.
