If Tau gun drones are equipped with pulse carbines, do they have
the under slung grenade launcher as well?

No they don't have under slung launchers. It says in the carbine text that it has a chance to take under slung grenade launchers. Then if you look in the text for pathfinders it says they may take them for 1 pt each But the gun drone has no listing for the grenades, also as a side note the carbines in the pictures are a little different where the grenade launcher would be.
