This would be tricky. The export code is only presented with buffer
version to be exported. All the :exports none/:exports results code
blocks are removed when we resolve links.

I like this idea better. See the attached patch.
After the patch, links to :exports both blocks will be ambiguous, unless
the results are explicitly named. So, I documented this detail in the
manual.
Let me know if there are any objections.
Best,

Subject: [PATCH] org-export: Make results of named code blocks a valid link
target
* lisp/ox.el (org-export-search-cells): Use #+RESULTS keyword as
search cell when #+NAME is not provided. Update the docstring
accordingly.
(org-export-resolve-fuzzy-link): Update the docstring.
* doc/org-manual.org (Exporting Code Blocks): Document the new
behavior and explain the details of exporting links to named code
blocks/results.
Fixes https://orgmode.org/list/010201826cb68597-bf75d596-7890-4dd0-b9ff-0c7b617b4dd4-000...@eu-west-1.amazonses.com

To stop Org from evaluating code blocks to speed exports, use the
header argument =:eval never-export= (see [[*Evaluating Code Blocks]]).
