I think the current state of the keyboard, is a safe state.

It's still better do discharge all juice.

I don't sit here worrying about the single cell 3.7V
battery inside each of my Bluetooth speakers. I do not hunger
to short them out :-) I know what size of resistor to use,
and I would also selected grabbers suited to the conductors
present in there. But there's just no need to drain it.

The battery should not be easily removable, a spring-loaded
battery holder should not be present in there.

So I cannot do it via the exposed USB-C port,
nor the USB-C plug of the keyboard cable?

If the design is intended to power other circuitry, it
can only discharge the cell down to 3.0V or so.

You haven't opened it up yet, to see what kind of
a mess is in there. With a keyboard PCB, the battery
and any other circuits, would be off to the side of
the key matrix. You should be able to see things well,
see how accessible the battery is, and so on.

Can I trick the circuitry (circuit board) into
believing that charging is actually discharging
using the exposed USB-C port or the keyboard's cable? :)

As I said in another branch of threads, I would have
to first unplug all the Cherry keycaps, Cherry MX
switches, unscrew then pile the plastic edges of the
caseing just to open the plastic casing!!

That's a lot of time, mood and patience! :)
