Below are the possible ways to rotate/rename listener.log files.

1) Stop the listener on a regular basis then you can simply rename the file at the OS level, then on next listener startup, a new one will be created.

2) If you have a 24X7 environment and the listener can not be stopped, then you can use the following steps to rename / move the file without having to restart it:

LSNRCTL>
LSNRCTL> set current_listener <listenername>
LSNRCTL> set log_status off

In another window rename the log file. Then return to previous window

LSNRCTL> set log_status on

which will create a new and empty listener.log file which will continue logging.
