Can Muslims be exempted from fasting in Ramadan?

There are exceptions - fasting is exempted for the following...

Yes. There are exceptions for children, the elderly, those who are ill, women who are pregnant, nursing or menstruating, and people traveling, which can include athletes during tournaments.
Many Muslims, particularly those living in the United States and Europe, are accepting and welcoming of others around them who aren't observing Ramadan.
However, non-Muslims or adult Muslims who eat in public during the day can be fined or even jailed in some Middle East countries, such as Saudi Arabia and the United Arab Emirates, which is home to large Western expat populations in Dubai and Abu Dhabi. In many predominantly Muslim countries like Indonesia, karaoke bars and nightclubs are closed across much of the country for the month.
Restaurants there use curtains to conceal customers who eat during the day.
And in Egypt, the Dar al-Ifta, which is the main authority in charge of issuing religious edicts, on Monday warned against eating in public, saying this is not an act of "personal freedom, but chaos - an assault on Islam."
In China, minority Uighur Muslims complain of heavy restrictions by the Communist Party, such as bans on fasting by party members, civil servants, teachers and students during Ramadan, as well as generally enforced bans on children attending mosques, women wearing veils and young men growing beards.
