I am not sure you could clean the disk to work well enough in your VIAO laptop.
They REALLY, REALLY make those OEM disks hardware sensitive... Hence why they only work on Dell and not Sony.
BUT all opinions aside, legally you can't do it as OEM software is tied to the hardware (The Dell PC) and in the EULA of the OS (Which you agreed to when you started\installed Windows for the first time, whether you had seen it or not

) it says that the Windows install is tied to the hardware.
So in effect, basically, YOU don't own the OEM copy. Your Dell PC does. I am sorry but that is the plain old sorry MS fact of it.
Quote from an actual MS email about the OEM EULA:
Quote
There is no difference between pre installed OEM operating system software and OEM operating system software acquired after the purchase of a PC. Regardless, the OEM operating system must remain with the device that retains the motherboard.
