Backup done in 16.04 LTS; restore possible in 17.10 LTS?

Yes. Deja dup should be able to restore backups made with its
first version.
That said, the situation you describe is probably best managed by just
copying files to a thumb drive / hard drive and copying over to the
new system.
Duplicity’s file format is optimized for incremental backups over time
and is over engineered for a planned system migration.
But it should work fine.
