Hello Amadeu and welcome to SL Forums. According the list of Oz Linden about which cards are supported, yes.

The second life works in Toshiba Satellite C660D-144?

If it supports OpenGL, yes.  How comfortable that is to use is another matter that you'll just have to find out for yourself if you have access to that GPU.
