Since it is a legal question it is usually always difficult to answer without creating problems. As it was said before, this is trademark law, which among other things tries to prevent confusion of the consumers and allows undisturbed branding for the trademark owner.
trademarks are also limited to certain sectors of business. If you are in an unrelated sector than the trademark owner, it is more likely that you don't violate trademark law.
In any case, you could also contact the trademark owner and ask them for their objections. If they don't have any, you should be clear.
DISCLAIMER: IAAL, however nothing in the statements above constitutes legal advice, but is solely meant for the academic discussion of a legal concept. It is advisable that you contact a practicing lawyer in your jurisdiction for concrete answers to your legal question!
