It is possible, yes.

If you look at (gnu packages linux), you’ll find this:

  (define* (kernel-config arch #:key variant)
    "Return the absolute file name of the Linux-Libre build configuration file
  for ARCH and optionally VARIANT, or #f if there is no such configuration."
     …)

  (define* (make-linux-libre version hash supported-systems
                             #:key
                             ;; A function that takes an arch and a variant.
                             ;; See kernel-config for an example.
                             (extra-version #f)
                             (configuration-file #f)
                             (defconfig "defconfig")
                             (extra-options %default-extra-linux-options)
                             (patches (list %boot-logo-patch)))
    (package
      …))

and later:

  (define-public linux-libre
    (make-linux-libre "4.8.11"
                      "04h3n3lw563i4yhxfkxrrwjvafd3af730l1ih9kqv7qwkm0psy7r"
                      %intel-compatible-systems
                      #:configuration-file kernel-config))

Currently ‘make-linux-libre’ is not public, but we could probably make
it public (David, WDYT?).  In the meantime, in your own module, you can
do:

  (define make-linux-libre
    ;; It’s private but I wanna use it anyway!
    (@@ (gnu packages linux) make-linux-libre))

HTH!
