If you have not been specifically prohibited from doing something as part of your order, then you may do it. You need to ensure that you do not miss any probation appointments. If you do because (say) you were stranded abroad, it could be held that you placed yourself in a position where you had a greater than usual chance of not being able to fulfil your committments. You could then be found to have broken your order and, in your case, the Suspended Sentence could be enacted.
