yes, that should work.  Try to export the following several times.  The
first number should not change.
(note: maybe you'd have to execute the inner_test_cached once on your
system)

#+name: inner_test_cached
#+begin_src R :cache yes :exports none
  rnorm(1)
#+end_src

#+results[dbeb7280be41fdc949815808cf601a6d01a400bb]: inner_test_cached
: 1.12399967834262

#+name: inner_test_not_cached
#+begin_src R :exports none
  rnorm(1)
#+end_src

#+results: inner_test_not_cached
: -0.562660468468834

#+name: test
#+begin_src latex :noweb yes
  \begin{equation}
    <<inner_test_cached()>>
    !=
    <<inner_test_not_cached()>>
  \end{equation}
#+end_src

Cheers,
Andreas
