I am kind of fascinated how people without computers end up at a coding school. Are they paying to attend?
That said, I have an elitebook 8470p and assuming they have ssds and enough ram, they should be fine considering the situation. If the 8460p is like the 8470p, the CPU is even a socketed one, so there's room for upgrades too, assuming they aren't already maxed out. Learning to make do with older, limited hardware can be a very educational and even enlightening experience.
