Depends. There's a "minimum wage" of sorts that warriors need to recruit and maintain a unit. Personally, I think it's around 80 gold per week. Bedwyr had it worked out to 55 per week, and I'm sure with some micromanagement you could drive it even lower. Still, the amount of gold available to the realm is the functional limiting factor, and Thalmarkin hit that like 5 nobles ago. So it's definitely possible.
'Course, the appropriate course of action in the above example is to expand...
