Well yes, there are some compounds that react with Oxygen that they themselves do not contain oxygen within. Combustion reactions only require oxygen to be reacted with, not a compound that contains oxygen. One example would be CH4 + 2O2-->CO2 + 2H2O. The compound does not contain oxygen but it is reacting with oxygen hence, it is combustion. Does that make sense?
