Hi Luke, I honestly don't have a solid answer for you - but my understanding is that you cannot use a name that is already in use in your state (in the U.S.) regardless of their industry, etc. I don't know how that plays into overseas companies.
I ran a Google search to see if I could find an answer for you and it does sound like the U.S. is a member of something called the WIPO which governs trademarks and copyrights internationally. The information at
the link I've shared here goes into some detail about what you can do and what you can't in terms of using a name that's already in use in another country. I hope this info helps a bit!
I'd be curious to find out what you learn

(from my understanding of the info at the link, unless the other company is considered 'famous', and assuming they don't have a copyright or business entity established here in the States, it would be ok for you to use the same name here in the States)
