In some companies, HR looks at the previous salary to approve an offer. You can convince them that the employee is worth it, but you have to have a good justification and it will probably involve approval by higher execs. You also have to compare the offer to what other employees in the same position in the company are making. If the offer is too different it will also require further justification.
