Cross reference between tabs, a bad practice?

It is known that in-page links can be confusing, but also are helpful to easily navigate through page content.

For tabs, there are some design guidelines too. A good article is this: "Tabs, Used Right" | Nielsen Norman Group.

It is not clear for me if is a bad practice, for example, a reference in the content of the first tab to the third tab.

Update: To make this more clear, let's take an example. We have 4 tabs with different sections of a store: movies | music | books | games. In the first tab, where I gave the newest movies, can I have a link to the third tab "related books"? I don't see the content from the two tabs simultaneously, but is ok to change the tabs in this way?
