No (well, in theory you could edit the QEMU sources and rebuild).
QEMU models what the real hardware provides, which in the case
of these dev boards is a very small amount of RAM.

It's empty space, effectively; there's no device and no RAM there.

The netduinoplus2 probably has more RAM and a Cortex-M4. QEMU
5.2 will also have an mps2-an386 model which will have 16MB
of RAM and a Cortex-M4.
