I don't think so. I made a successful test with a 100M sparseFile like
yours, but you have to give the --sparse option to borg.

In short (under /tmp):

    borg init --encryption none /tmp/borg/repo

    borg create --sparse /tmp/borg/repo::sparseFile sparseFile

    cd ../dst
    borg extract --sparse /tmp/borg/repo::sparseFile sparseFile

    du -m ../dst/sparseFile
    0       ../dst/sparseFile
