Most ARE shot from full choke- or even Extra Full Choke.
Unless it is a full choke, the answer is generally yes.
That will depend on whether the choke tube is rated for steel shot or not.

Can you Yes, should you NO. a full choke should not be used to shoot slugs.
No.
If it was made to shoot steel shot and has interchangeable chokes.
A rifled slug- yes.
because the choke is actually slightly smaller in diameter than the barre, for tightening the grouping of shot shells. A slug will cause major problems.
No, you do not want to shoot Black Cloud Ammunition through a wad constricting choke tube. With any factory choke you will be fine, otherwise companys like Patternmaster Choke Tubes make a choke specially for Black Cloud.
Never fire a shotgun without a choke tube installed. DANGER, DANGER, DANGER
Simply put, no.
