How to remove the wrong link and add the right link?
You can't unless you have a gold badge for one of the tags applied to the question.
You might ping a close voter who has that privilege to add your link (and maybe remove the original one).
Another option is to ask for that at the site specific Meta site.
You can also edit your question and add the link to the duplicate you found yourself, along with a description why that works better for you than the originally chosen duplicate.
The latter method would have the advantage that the question is bumped to the home page (active tab) of the site, and might receive more attention from users who could add or replace the duplicate link.
