Yes. But that's easy, as there's no configuration involved.

If you use eg. network manager or wicd, you can use the gui-config tools 
that come with these programmes. Else you have to set 
/etc/networks/interfaces (see man interfaces)
Use either the 10.x.x.x or 192.168.x.x range, these ranges are for 
private use. Configure eg the two pc's as
192.168.0.1, netmask 255.255.255.0
192.168.0.2, netmask 255.255.255.0
And then you can connect from 192.168.0.1 with `ssh 192.168.0.2' and 
vice versa.
Yet, I still recommend buying a router (eg. a linksys) and use dhcp to 
configure the stuff. Such a router also allows sharing the internet 
connection, firewalling your private network and so on. On the config 
page of such routers you can usually statically set the dhcp-lease, so 
the ip's don't change. Some also have a dns server, so you can actually 
name the pc's and ssh with the name you've set in the dns. If you like 
to experiment, buy a router that allows running Openwrt or Debian for 
the arm processor. Then you have a complete linux running on your router 
and you can control even more. Yet, considering that you currently don't 
know how to connect two computers this might be a step too far.
