That depends on your definition of "work".
I have an HD XL image that I put on a drive and stuck in an HD just as an experiment, and it sort of booted, but if I'd let it connect to the TiVo servers I'm sure it would have led to disaster in short order.
If that HD XL is on monthly, that lifetimed HD will qualify you for the MSD deduction on the XL.
Of course if your goal is to retire the XL and save the monthly payment and avoid laying out any cash for a bigger drive for the HD, then it's doable, but you'll need a PC to which you can attach hard drives other than the one you boot it from.
You should make a backup truncated image off of the 1TB drive out of the XL.
Then you can overwrite the XL's drive with the stuff on the HD's drive, and then expand into the other 840GB.
But if you can afford it, I'd recommend finding a new WD20EURS 2TB drive on sale somewhere for around $100 and putting that into the lifetimed HD.
You'll have twice as much space on a new drive with a 3 year warranty.
