I think this is really a subtrope of Androids Have Human Biology. (For the subtrope, Headshots Kill Robots is not bad enough to change.)
It's more inclusive than Headshots kill robots. Look at the definition: Robiots vital systems are usually intheir heads. We have examples of robot's heads being disconnected and still functioning, robots having their heads switched and still functioning, robots being killed by destroying their heads. Now, which of those does the name imply? Only the last one. The name is misleading because it is too narrow. It's like naming a trope "Rottweilers" when it's about "any guard dog".
Hmm, in a slightly quirky frame of mind, how about Where Do Robots Keep Their Brains?.
"It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"The name was mostly put in because it rhymed. During YKTTW, I asked if anyone had something better or objected to the title. No one seemed particularly concerned about it. I'm still open to the idea of other names, as I was then, I just couldn't anything that was descriptive and not clunky.
Headshots kill Robots.
A better rhyme might be, however, Shots To The Head Kill Robots Dead.

Shots To The Head Kill Robots Dead is a good rhyme but the original title is more concise while still rhyming.
I personally don't care much for the rhyming but the title makes sense to me as a subtrope.
Crown Description:

I thought Headshots Kill Robots meant, well, shooting robots in the head. Or at least shooting them where it wouldn't logically kill them and it does.
What about Head Swap Robot or Does This Head Look Good On Me?
I'm on the internet. My arguments are invalid.
