I am unsure if there are OS updates for that calculator, but if you mean for example installing a FX-9750GII or 9860GII OS I doubt it would work because of hardware differences, particularly the smaller 7400g series screen.

The fx-7400GII uses the same 128x64 resolution. Only the PPI value is higher.
The real problem is that the ROM size is only 2 MB and fx-9750GII and fx-9860GII OSes need 2.5 MB at least.

OS updating is inofficially supported, but there are no newer OS versions available that we know of.

Oh ok, I thought the screen was smaller, since the 7400g+ screen is several pixels smaller. (80x48 pixels)
