It is possible, but as Dave Noble and I have been trying to tell you, it is against Emirates terms and conditions to do so, and if they find out, they will cancel your ticket, and you will be denied boarding without a refund.
You should find out exactly what he is doing, and if he isn't booking you an actual business class ticket, cancel and book somewhere else.
I would report him to EK as well, as he might be ripping many other people off too.
