If you point a burning laser pointer at the satellite and it picks it up zoomed in on you could you damage the satellite?
Maybe? I think the real question is if you're more likely to score a direct hit or win the lottery? Of course if it is "burning" you probably don't want to hold on to it for long enough to try.
And you certainly don't want to go waving it around in the air...
Why not give it a try?
After all, they're only moving at 7.5kms-1
In the United States, it is a fine-able offense to shine laser pointers at the cockpits of airplanes. http://usgovinfo.about.com/od/consumerawareness/a/Fine-For-Pointing-Laser-At-Airplane.htm
