No.  Listing a library in a Requires: tag at all is an explicit requires.
ie:
Requires: libmysqlclient.so

is also not allowed.

RPM is generally good about discovering what libraries a program needs to
run.  So it will find that your program needs libmysqlclient.so.16 and
create a Requires on it automatically.  You do not need to list it in your
package if this is the case.
