Yes, you just need to arrange for a client to make separate requests using different Client-IDs
BTW, using eth0:1 for additional addresses is rather outdated - and IME of little utility. All I've ever done for years is just add the addresses to the base interface, as in :
ip addr add a.b.c.d/nn dev eth0
Also note that you cannot bind a DHCP client to such an interface either. Since it has to handle broadcast messages, the system is unable to differentiate between broadcast messages to be handled by eth0 and broadcast messages to be handled by eth0:1.
