Yes!: Stress can cause vomiting. However, so can a lot of other things. If you have vomited up any blood, lost weight, missed a period, or have any pain associated with the vomiting you should get checked by a doctor. If you can't control the stress you have, try exercise, learning to meditate, get 8 hours of sleep at night and see if that helps. You could also try counselling.
