If I were trying it, I would insert the .lnk file into an emacs buffer
and then return the buffer as a string.  Something like this perhaps:

(defun lnk-as-string (lnk-file)
  (with-temp-buffer
    (insert-file lnk-file)
    (buffer-string)))

And then use the ordinary aref or subseq functions to access each
bytes:

(let ((lnk (lnk-as-string "/bin/ls")))
  (subseq lnk 1 4)) => "ELF"
