A lot depends on the commercial aspect.
Do you expect to make money from it ?
Arduino is something of a niche market so I would not expect to see a lot of hits.
There are a few FB groups using the "Arduino" in the title that are quite active and AFAIK they have not been hit with any cease and desist orders.
Clearly trying to "misrepresent yourself" as affiliated with or part of the official Arduino platform could draw unwanted legal attention but as a personal venture then from my POV there is no harm.
There is more documentation available for this aspect on this site so maybe you want to dig around a little more and catch up on what Arduino organisation expect from people using the name and or logo's.
