Hypothetical NSmen deferrment scenario

Let's say hypothetically, I deferred for a low key ICT due to the ICT date clashing with my school timetable and I have already secured a deferrment for the ICT. Now after a couple of weeks from getting the deferrment, I went to get a gap year from the school and now I am no longer in school. But I have "forgotten" to tell my superiors that I am no longer in school for the time being. Would I be in trouble for not telling superior that I should override going back to reservist and nullify my deferrment result?
