People can still find the business by searching "<businessname> repair shop" as well as possibly "repair ship <cityname>" but the issue is not being able to advertise on terms like "fix iphone 8" or "ifixit iphone".
Where the problems come in is when the actual name of the business includes a third party trademark. Try calling your business "Joe's Cut-Rate Porsche Service" and you can expect a C&D order.
I'd probably be a bit nervous about taking my Ferrari to Joe's Ferrari Service though.
