I studied Linguistics at a university level, so I can be pretty certain about most of my linguistic knowledge. The word noble could indeed be transcribed into other languages, but in this case it is nonsense because:
a) 'nobyl' is a highly unlikely form for it to take; and
b) the 'no' in 'nobyl' is part of the element 'cherno', so the second element is 'byl' not 'nobyl'.
As this is a facts board the rest of us try not to make blind guesses unless we have some solid evidence to back them up.
