Yes, you can. It makes sense. It would be understood. And it doesn't suggest anything wrong.
However, it may not be the best choice of words.
1) It is slang, not standard English.
2) To "get a kick" suggests a very intense pleasure. It suggests a pleasure that lasts for a short time. It feels like you've been physically hit. The pleasure you get from language learning is usually a long, calm, lasting pleasure.
3) It is hard to be sure, but I think "to get a kick" may be a little old-fashioned. That happens with slang.
I get a kick out of....
Er, what DO I get a kick out of?
When I was young I got a kick out of a lot of things. Nowadays, sadly, not much gives me a kick.
It's correct and so is Dan. Not everyone is going to understand it, but that just gives you an opportunity to teach someone something new (or old :))
Like Dan said, it suggests something a little more action packed than learning languages, but it's slang and can be used pretty loosely.
