Thameslink have notices up specifying in which area you can use
Oysters. Roughly speaking it is at stations between West Hampstead and
Elephant and Castle. Probably London Bridge as well, BICBW.

Yes, the question was not whether Oyster Pre-Pay could be used, but how it
is supposed to be used. There are validators on the Thameslink platforms
and at least one end of the tube platforms. If transferring between
Thameslink and tube using a Pre-Pay Oyster is one supposed to use the
validator on both Thameslink and tube platforms, or will just one or the
other suffice?

You only need to touch in or out of the system when you enter or leave
it. Transferring between lines does not need a touch in/out. If you
are continuing past the limits of the system, then you need to touch
out on joining Thameslink.
