Deleting a page that's included in my brand's search site links?

When you google my website/brand name, Google shows the homepage but also 6 sub-pages, which I think is called sitelinks.

My question: I want to delete one page. It's no longer necessary or relevant for my site/brand to have.

Is there any harm in deleting this? I assume Google will see the "404" page and adjust, either removing it from sitelinks or replacing it with something else?

Or is there more risk here that I'm not seeing?
