Nope, you can't. You could tore it apart more though.

I could post pics of my destroyed calc.
The one I gave you? O.O
Yep. It was already pretty much destroyed anyway. Well, I tore every part apart, it was kinda easy.
Lol not really, all I did was scrambling the keys and getting rid of the cover, right? :P I don't remember since I didn't touch it for 8 years.

Yeah, pretty much. All I did is opening it and taking the LCD apart to analyze it.

Also something fun: there's only 2 wires on the board, you plug one to +3.3V and the other to the ground and it works :)

And the LCD only needs the ground and a finger (O_o).

Ah I see. I wonder if the parts could be re-used for other stuff...

You can easily reuse the LCD, but it takes something like 25 wires.

The board too, you could use it as input and wire where the LCD was to a circuit or something.

I just found out more stuff. The foamed up battery slot does have terminals running to the circuit board but does not have any contacts on it. Aaaaand the circuit board is riveted to the case. With rivets. That I can't break off.

Wow, the way this calc software works is like if they ripped one of Casio's oldest graphing calc models. My FX-7000G operated in a similar way and you even had the MODE legend on the case like on this one.

It may indeed be a rebranded Casio, given the similarity. It's not uncommon for the manufacturer to be totally different from the brand name printed on the case. Often manufacturers will make products and sell them to other companies just so that they can put their own name on them and resell them.
