Something like this should do the trick:
$ zgrep "\[ 0.000000] Linux version" /var/log/kern.log*
Provided that the files actually go back that far, in the default
logrotate configuration only the last four weeks of kernel logs are
kept.

There is no /var/log/dmesg file with systemd because it is redundant,
all that info is in the journal (and in the other log files like
/var/log/kern.log if you have a syslog daemon installed).
