Yes, nagios uses the archived log files for historical reporting
(availability, etc) and expects them to have a particular name and be in
a particular location. If you modify either then you break the reports*.
Since the furthest time period you can go back in the reports is 'Last
Year', you'd need at most 2 years of log files to obtain accurate
reports. If you don't need reporting for that long, it's a simple matter
to use find to remove or move old logs.

* location is special in that you can specify the directory that
contains all the archive log files in nagios.cfg
