As John says, _if_ it can do pxe then you can install. You'll need a properly 
configured dhcp/pxe server, the vmlinux and initrd.img files from 
4.4/os/xxx/images/pxeboot, pxelinux (from the syslinux package) and a 
suitable pxelinux config.

minimal pxelinux.cfg example (assuming the pxeboot files mentioned above lives 
in /tftpboot or equiv on your server):
LABEL c4_install
        KERNEL vmlinuz
        APPEND initrd=initrd.img

The doc files that comes with the syslinux package are good 
(/usr/share/doc/syslinux-2.11/pxelinux.doc for example). 

good luck,
 Peter
