Can you use your Oyster card for Pay-as-You-Go from London Bridge to
Tundbridge Wells?

Thanks in advance.

No. The "London's rail and Tube services" map shows the extent of
Oyster-land with a black dotted/broken line:

From which we can see that the number of places outside the classic
"Zones" is really rather small.
