Definitily not.

There is a bit of electronics between the cables power-lines and the 
battery - to make sure that the battery doesn't load to fast and not gets 
over/under charged (both can kill a battery rather quickly), and also to 
make sure that when the connector pins *accidentily* gets short-circuited 
you don't end up with a laptop-bag or backpack bursting into flames (or just 
fries the keyboards electronics).

And for the record : you should *never* short-circuit a battery (or any 
power-source for that matter).

But as asked, why do you think you should discharge the keyboards battery to 
begin with ?
