Have PC & Netbook. NIS on PC, can I use same license to run Norton Netbook?

Okay, first time poster here.  I have Norton Internet Security 2009 on my PC.  I just bought a netbook and downloaded Norton Internet Security 2010 for it and am using the same license as my PC.  However, this program is HUGE on my netbook.  Can I run the Norton for netbooks with the same license?
