0x0F 0x04 looks like it's available. It's marked as invalid which I assume means it's reserved in case they want to wedge more instructions in there, but it should be fine for you to use. My pdfs are a few years old so there may be some fancy new instruction that goes there, but you should be safe ignoring that.
