at least the wpa_supplicant binary on the Kobo mentions both PEAP and MSCHAPV2, so some kind of support might be there?

but since I don't have access to such a wifi network there's no way for me to try and see if it could be made to work (by changing /etc/wpa_supplicant/conf or whatever)

ctrl_interface=/var/run/wpa_supplicant
update_config=1

# example from wpa_supplicant man page
network={
	ssid="example"
	scan_ssid=1
	key_mgmt=WPA-EAP
	eap=PEAP
	identity="user@example.com"
	password="foobar"
	ca_cert="/etc/cert/ca.pem" # you have to provide this file yourself
	phase1="peaplabel=0"
	phase2="auth=MSCHAPV2"
}
