You can stay overnight as long as you don't exceed 24 hours (presuming this is the stopover rule).
Assuming you are taking CX 731 from HKG-DXB then you should be fine. Also I think you should overnight this as I did F Class on the SIN-HKG before as find the experience to be much better than the 773 and you get to spend a night in HKG!! go out and visit HKG! The CX F Class experience is so much different compare to any other F Class flights for this duration in Oneworld. However just to let you know you won't get PJs, Amenity kits, Caviar. A Grey Woolen Blanket will be provided upon request.
OH jsut another word of warning I think the HKG-DXB flight sometimes get substituted to a 2 Class (dreaded NRBC) even for the nonstop!
