Yes. This is the 'Open Jaw: one allowed' in the 25K standard domestic award. (OK, or the 45K standard F, or higher mileage level Easypass awards.)

But you will have to call (or else you can put a similar award, such as LAX-EWR return, on hold, and then call co.com support at 1-800-300-1547 to have them change it for you, and put it back on hold for you so you can purchase online, if you would prefer to avoid the phone ticketing fee and do not get it waived because you are not a Plat).
