I don't think you are, but is the trainer aware of the scheduling conflicts that took place in your company to accommodate this training?  I would politely explain that rescheduling is not an option at this late a date.  If he is unable to meet his first commitment to you, is another trainer available from their company?
If he still pushed for a change my response for be:  he has already made a commitment to your company and a change at this late date will leave a very unfavorable impression on the professionalism of his company.
Tough situation but I am sure you will handle professionally.
