Grown up with age, note, can be corrupt (10)
I believe the answer is:
adulterate
'be corrupt' is the definition.
(thesaurus)
'grown up with age note' is the wordplay.
'grown up' becomes 'adult' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'age' becomes 'era' (I've seen this before).
'note' becomes 'te' (**).
'adult'+'era'+'te'='ADULTERATE'
'can' acts as a link.
(Other definitions for adulterate that I've seen before include "Spoil" , "Make impure by addition" , "Debase by mixing with something inferior" , "Corrupt" , "add inferior material?" .)
