If I make a character with two cyberarms, each of them containing a cyberarm gyromount, can the character utilize both mounts when firing a two-handed weapon such as an LMG?

This is in the wrong thread. It should be in previous editions.

[McGuffin]

No, only one system will provide the bonus. But keep in mind that the gyromount negates movement and recoil modifiers (not one or the other, both).
Meaning you can run and gun without worry

They can however make it difficult to change direction quickly while remaining at speed.  Slowing down before you turn might be advisable.
