> 僕は20歳大学生。

I feel that 20歳 is used as an adjective here. Is there any special
conjugation?

Correct grammar? 「僕は20歳大学生。」
It's possible but people will probably still expect something in between the 歳
and the 大 even if just a space or a comma:

> この時僕は20歳 大学生。

> 僕は20歳、大学生の時に起業したんですが、

> 僕は20歳大学生の男です。

> I feel that 20歳 is used as an adjective here.

Well, he could say he was 20 years old without the university student bit, so
I'm not so sure about that.
