@frellan It doesn't work because apply returns the receiver, not the result. You want let or run.

val maybeFiltered = collection.let { if (boolean) it.filter { ... } else it }
// or
val maybeFiltered = collection.run { if (boolean) filter { ... } else this }

Note that filter returns a new list, and does not filter in place.
