This is an old theory that is no longer supported by most paleontologists AFAIK. Trunks require specific musculature, more blood vessels, and more nerves than a regular nose does, and those things leave evidence in the structure of the facial bones.

I’m no scientist and I’ve never seen one in real life, but I can promise you penguins do not have trunks iirc
