You can't really delete it - it will just come back!
If you're using a theme that has both a Home screen (screen with a few icons) and an Applications screen (screen filled with icons when you click a specific icon), get to the Applications screen.
Now, highlight the Yahoo icon, hold down the [Alt] key and Click the Scroll Wheel, and select Hide Icon.
Once one or more icons is hidden, [Alt]Click will also have the Show All option.
To unhide an icon, use [Alt]Click --> Show All (to uncheck that option), go to the hidden icon and use [Alt]Click --> Hide Icon to uncheck that option.
