[Harry Potter] Would Parseltongue be able to distinguish between a Slow-worm and a "true" snake?

Technically, slow-worms are limbless lizards instead of snakes.

Parseltongue is a language. It's not sentient. Your question is flawed. You should ask, "Can a slow-worm understand Parseltongue?" The answer is no. 

You may as well ask if your glass mug can distinguish between a full-grown dragon and some butterbeer. No, but butterbeer will fit in the mug and a dragon would not. This is a very Muggle sounding question. Are you a Mudblood?
