Yes, you can leave with them.
If you plan on using the rest of your ticket, you will want to read the airline's CoC and the fare rules of your ticket; most carriers will invalidate a ticket and cancel a reservation in the case of a no-show requiring a new ticket to be bought, perhaps using the invalidated ticket as a credit.
