On the geometry dial, cut out value something like 0.0001 might help.

^ setting Cutout Opacity at a very low value does indeed make the object invisible while keeping the emitted light, you should try it. But it does change the reflections. The emissive box will disappear from the reflections in surrounding objects. The result can at times look unnatural.

Another way is to render twice - once with the box visible, once without - and combine the results afterwards. You can use the Spot Render tool so you don't have to render the entire thing twice.

This example is made by rendering twice to get a reflection that doesn't match up with it's surroundings:
