Bit more than that <https://manpages.debian.org/kexec_load(2)>:

    The kexec_load() system call loads a new kernel that can be
    executed later by reboot(2).

And one of the functions of the latter
<https://manpages.debian.org/reboot(2)> is:

    LINUX_REBOOT_CMD_KEXEC
      (RB_KEXEC, 0x45584543, since Linux 2.6.13). Execute a kernel
      that has been loaded earlier with kexec_load(2).
