Nope. The iso boots into "normal" text mode, the window can be increased, but the active view is not increasing. This procedure works:
1. boot the iso
2. Switch to second pty (Ctrl-Alt-F2)
3. Find management interface (ip a)
4. Configure ip address (ip addr add 192.168.xxx.yyy/24 dev <interfacename>)
5. Activate interface (ip link set <interfacename> up)
6. SSH into the node (username: rancher , password: rancher)
7. sudo -i
8. /usr/bin/start-installer.sh
9. Don't select DHCP if you have it because it will override the manually configured IP. When the installer is crashing, increase the window size of the terminal and retry the installer
