As per the official blog

Token Invalidation

Now you can invalidate an OAuth token for your application. Just send an OAuth signed GET request to:

https://api.linkedin.com/uas/oauth/invalidateToken

A 200 response indicates that the token was successfully invalidated.

However as per this :

Third party applications do not have any way to log a user out from
LinkedIn – this is controlled by the website. Invalidating the token
makes the user re-authorize the next time they try to use the
application, but once they have logged into LinkedIn their browser
will remain logged in until they log out via the website.

So In conclusion : as of this date of writing, Linked In does not give this support to 3rd Party Applications
