Yes you can do this because a category certificate issued by central government is valid in all states of India only in that cases if you are taking admission via national level examination but if you are from another state and trying to take admission via state entrance level examinations then I must tell you that only candidates who had given 12th examination in that state are considered candidates of that state and get privileged of having category certificate otherwise outer state candidates are counted as general even if they belong to any category.
