No, it is not supported.

It did exactly what --help says:

$ busybox crontab --help
BusyBox v1.19.0.git (2011-01-18 13:36:16 CET) multi-call binary.

Usage: crontab [-c DIR] [-u USER] [-ler]|[FILE]

        -c      Crontab directory
        -u      User
        -l      List crontab
        -e      Edit crontab
        -r      Delete crontab
        FILE    Replace crontab by FILE ('-': stdin)


that is, it copied FILE (=/etc/crontab here) into crontab for current user.
