It would be a crime anywhere, but not likely to receive a 10-year sentence. As far as I know, the only sentence approaching that length issued in Denmark for a non-violent crime in recent years was Stein Bagger, who was sentenced to 7 years for defrauding investors of about $250 million, then fleeing to Dubai. His sentence was that high because it was very clearly willful fraud on a large scale intended to enrich himself, and included a number of subsidiary elements such as invented degrees, faked financial information, tax fraud, etc.
