You can determine this by removing the top cap from your steerer tube (if your stem is securely tightened, this won't change your headset adjustment) and looking to see if the top of the steering column is recessed 3-5 mm. If it's not recessed, then the headset can't be adjusted properly. If recessed too much, then the stem attachment might not be safe.
All good if it's an alloy steer tube. Park Tools (and others) are saying that for carbon steer tubes, it's better to have a couple millimeters of steer tube above the stem, and a 5mm stack spacer to keep the headset bearing preload correct.

I'll trust Park Tools on this one.
