Yes you can, I looked it up when I used the C++ and C# Express versions
at my previous employer.
It's surprisingly hard to find some actual legal text from microsoft's
VS Express website confirming or denying this.
There is a paragraph in their EULA which says:
"Unless otherwise specified, the Services are for your personal and
non-commercial use. You may not modify, copy, distribute, transmit,
display, perform, reproduce, publish, license, create derivative works
from, transfer, or sell any information, software, products or services
obtained from the Services."
The FAQ page for VS Express tells (in rather non-legalese, which in
this particular case is actually a bad thing because it gives no
reference to the actual details of the usage license) that you *can* use
it for commercial purposes.
Besides the EULA and the FAQ being contradictory, I can't find any
answer to the question of whether you can use it in a company for
commercial purposes, or whether the commercial usage is limited to
individuals only.
