Can I connect 2 computers to the internet in different areas of my house?

The problem is the 2nd router. You need a switch instead. The 2nd router has a "firewall" that is preventing you from connecting. The solution is to disable the router functions (specifically, the DHCP server and modem. Technically difficult.), thus turning it into a switch, or simply buy a switch. A switch has Ethernet ports only, no WAN connection, and no internal smarts. I recently picked up an industrial grade 24 port router at a thrift store for pennies on the dollar. Once I disabled the internal DHCP server and hooked to a port on my DSL device, I had room for expansion beyond the 4 ports on my DSL device. I took a very smart device and turned it into a dumb switch for the same out of pocket cost. The thing is, if I ever start my own ISP, I can turn it back into a smart device.
