Hong Kong AE round trip and single trip ticker voucher

I have purchased AE round trip ticker voucher and single trip ticker voucher to HK station, as at that time of purchasing, I have not booked the hotel, hence purchased the ticker voucher to HK station. My hotel ends up at Kowloon. Can I exit Kowloon station using AE ticker to HK station? or Can I change the ticket to Kowloon using ticket voucher to HK station?
