Can I add my own instruction set extensions to the original x86 isa as implemented by the 8086 without permission from Intel and / or AMD as long as I'm not copying any x86 instruction set extensions?

I don't know the legal details here but I think you can do whatever you want as long as you're not violating any patents (good luck). Also, Intel claims a copyright on the mnemonics for 8080 and 8086 assembly language. Microcode is also protected by copyright.
