Yes, if they find out about the undisclosed offense you could be denied and deported. People have been deported for failing to disclose criminal offenses (although because yours was less severe maybe that won't happen ... and if you weren't found guilty nor admitted to guilt you'll probably be able to keep your GC). If they pursue deportation, in your defense you could say that because you were told it was stricken from the record you thought you didn't have to mention it ... people have had varying levels of success and failure with that approach. Consult a lawyer ASAP before notifying USCIS about the situation.
