Answer 1

That's because Rename-Computer was introduced in Powershell 3.0

Answer 2

To do this in PowerShell 2.0, use WMI:

(Get-WmiObject Win32_ComputerSystem).Rename('PC02')

You can rename a remote computer by adding -ComputerName CURRENTNAME after Get-WmiObject.

You must do this from an elevated prompt. This will, of course, require a reboot to take effect.
