Hi Guys, 

I know that not what you're asking, but here is a module we used for several clients and did the trick :

https://addons.prestashop.com/en/accounting-invoicing/24986-facturare-persoana-fizica-sau-juridica.html#overview (the module is for the Romanian market but has an Eng doc) 

The module will split on the checkout the option for any client to place an order as a standard non B2B client or a B2B client. 

The request that you had can be solved as well, unfortunately as it's a checkout process the Js which will check if the fields contains data, and will make the other field appear, would take more time that the above module price  

I hope it help, 

Regard's, 

Leo
