Sure. CL certainly supports a functional programming style, and there are some good libraries designed for this, and it certainly lends itself more to functional programming than python. But CL isn't a functional programming language the way haskell, or even other lisps like scheme and clojure, are. CL is really a multi-paradigm language. You can use it for FP, or OOP, or straight imperative, and probably some other less-mainstream paradigm. It's up to you.
