Do you mean a plugin as in the browser? No, you will need a plugin to run Silverlight in IE10 on the deskop, and you cannot use Silverlight (or Flash, or any other plugin) when IE10 is in its tablet-style Metro mode.
The new WinRT API that Windows 8 is built on is very similar to Silverlight/.NET but is not totally compatible so it requires code changes. Most SL programmers will be able to find their way around pretty easily though. The UI guidelines for Metro have changed quite a bit so there are more considerations than just porting code.
