Yes, but you need to be an admin. There is a tag called  which can allow you to insert HTML into a page, but it has limitations.

Do you have some example HTML you might use?

Basically what you need to do is create a new MediaWiki: page like MediaWiki:SWFembedded1 and put the HTML on that page. After you've done that, you put  on the page where you want the content to appear.

This method is pretty simple, but doesn't really allow dynamic content or use of templates in the MediaWiki: page.

As always, the more info you give (like a link to an sandbox page or something), the easier it is to answer your question.
