Yes, and to be fair the OP doesn't even need to expose a port on his home network. He can do the opposite and have the port exposed on the VPS and have the local router / server connect to the VPS endpoint instead. This will also remove the issues caused by having dynamic IPs at home as well.
And that's a different animal (moving the goalposts, which is an excellent idea, but OP didn't even think of doing this).
OP asked about exposing a local port, which is a Bad Idea 99.9% of the time, especially for someone asking why it's a risk.
Using a VPS with reverse proxy is an excellent approach to adding a layer between the real resource and the public internet.
