From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You have no control over how an adversary accesses the drive, so no.
However, if it's enough to erase the data if wrong key is entered AND the original operating system is running it should be possible. But I agree, that limitation doesn't really make sense in a security point of view.
Besides that, I believe that luks encryption with sufficiently complex password (and updates) is practically the same than empty drive for the attacker. More interesting setup would be to give out different data depending on which key is given, there was some windows-based software which could do that back in the day, I'm not sure if it's still around and don't remember the name for it right now.
It would at least add a layer of obfuscation if someone extorts a key from the owner.
