The major difference between static sites and dynamic sites is the location of the content. In a statiic site, the content is written directly to the page as part of the HTML code, and is therefore, coupled directly to the appearance of each page. In a dynamic site, the content is contained in a database separate from the framework of the page and is accessed by the browser on the fly as the page is loaded through the code of the site. It is this separation of content into a backend that allows for themes to be used interchangably on dynamic sites.
While a very small site might be be easily built as a static site, in most cases, it is still easier and faster to build such a site dynamically by using a CMS system such as WordPress or Drupal. Sites developed with a CMS framework can be easily modified by the site owner and can allow even a novice to the web an easy upgrade path. Custom themes will allow the site to stand out easily from its peers and still maintain the ease of use.
To answer the original question of redirection of a static page to a dynamic page: yes it can be redirected, just the same as any other page would be redirected. In many cases, a dynamic site (assuming it is being developed by someone who knows what they are doing) will make use of 'clean URLS' which allow the page to be accessed through rewritten addresses of words instead of numeric page IDs. Browse to the page to which you want the original page to redirect, note its URL and use that URL in your redirection cod eofn the original static page.
