Yes, DHCP servers can easily server multiple /locally/ /attached/
subnets. As in multiple physical interfaces and / or multiple logical
VLAN interfaces. Wherein the DHCP server is in the same broadcast
domain as the DHCP client.
The don't need to be if a DHCP agent is available. DHCP agents are
considerably easier to implement AND don't need persistent state. They
can just be implemented in "less intellgent" network devices. This
also considerably eases exchange of defective devices since you don't
lose state unless it's the DHCP server itself that is exchanged.
The key is that the routers between each subnet and the DHCP machine
need to be told to route DHCP in some way.

I would consider those to be remote subnets as they are not /locally/
/attached/ to the DHCP server. Meaning the DHCP server is not directly
participating in the broadcast domain.

Being in the layer 2 broadcast domain means that everybody smells it
when somebody farts for a browse maser election on the other side of the
room.
That is unneccesarily confusing, DHCP has nothing to do with browse
master elections. I surely hope that Windows doesn't do those any
more.
