Of course.

To the "remote" machine the VPN connection is simply a nice hole in 
your corporate firewall.  It's not called a "tunnel" for nothing...

Whether a virus at the far end of a VPN connection can/will _infect_ 
anything "internal" depends on how up-to-date your internal AV is 
relative to the virus, how the virus infects and precisely how your 
antivirus works and is configured.
