Take a look at this thread: http://community.secondlife.com/t5/Second-Life-Vie
It talks about an MS Surface Pro running Win8 and SL.

My understanding of RT is that you can only install applications listed in the Microsoft App Store/Marketplace. Second Life is not in this.
RT is also mostly installed on low-spec systems like tablets. I would highly doubt that - even if it can be installed - it could run.
I would skip it.
