Thanks for your post.
The LDO's abs max is 45V, operation range is 8V to 40V, so 12V should be no problem.
I'm only affraid that the schematics shows not all 9V-Connections.
And btw, some ExtBoards for the prototype connectors (SantaCruz-Connector) want
12V. Is this standard?

It's not just the input voltage range, but the power dissipated (voltage dropped by the regulator * the current delivered).
The 9V input might have been chosen because of this. You could try 12V and it the regulators get hot glue on something
to act as a heatsink.
Not very pretty but if it's just to allow you to use the board.....
