Not exactly the same situation, but I used to remote into my home PC from work. I set up the firewall to only allow the RD connection from my work proxy IP. I didn't want the whole world having a shot and getting into my PC. I would think you could do the same thing whether it be limiting your work PC RD from your home IP or if the IP changes often, you could at least only allow the RD connection from the subnet that your DHCP address comes out of. Even if you don't have access to the corp firewall to do that, you could always use the firewall that's built into Windows. It's better than nothing.
