The amplification of Rule 21.1 lists the reserved identifiers and names that are covered by this rule. This mainly covers identifiers / names found in section 7 of the library, but also includes "defined" as you mention.
Keywords ( e.g. int , typedef . . ) are not "reserved identifiers" and are not covered by this rule. However, any attempt to use #define on a keyword will violate rule 20.4
"A macro shall not be defined with the same name as a keyword"
