two installs

Hi,
 
I've always tested The Bat at my work-PC, so, in 'real' use, never in a 
separate testing envirroment. When I'm on the road, I check my mail 
by using a browser and logging in directly at the mailserver, because 
the work-pc at home is down.
On the road (meetings, vacation, etc.) I've my tablet/notebook with me.
Question:
Is it legal to install The Bat also on my travel-pc to check my mail?
(I've used Voyager, but that does not work well for me).

Kind regards,
