It's safe, but there might not be space in the fork for the large diameter of the nut to reach all the way forward to the bolt. If it fits with at least 6 full turns of thread engagement, it's OK. The nut is actually stronger than the bolt, but the brake load is reacted through both whatever their respective lengths.
It's possible to swap the brake centre bolt③ for a longer one, although if it's locked in with a grub screw② the operation can fail resulting in death (of the caliper, not the cyclist). I can't find a picture of the underside of the SRAM Force body, but the general layout will be the same as other dual-pivots. The grub screw can be over-tightened at the factory, deforming the M7 thread on the centre bolt, which then gouges the soft aluminium female thread in the brake caliper body when you undo the centre bolt for removal.
