Non-furnishing of NOC for job shifts before the completion of certain years of service in the organization is a rule to reduce frequent employee turn over only. However, such a rule cannot extinguish the right of the employee to resign when a better opportunity is available to him/her. Still, while applying for some other job particularly in some other Government company, you could have asked for NOC as a special case and upon refusal, if any, you could have mentioned in your application to the new job and should not have skipped the information.
