Can I erase the 400 Go of LrLibrary in my Imac ?

Thanks. Alexander

Yes, but it's best to make sure sync to the cloud is fully completed first.

As @selondon says, yes you can delete the Library (provided all syncing is up to date), but understand that when you next start the Lightroom app it will rebuild the Library (using the catalog in the cloud) so some of that 400GB of data will be recreated on the iMac.

400GB is in fact quite a large size, so I suspect that much of that is being taken up with locally stored originals (these are stored by default within the local Library). While the local Library cannot be moved to a different drive, it is however possible to redirect the originals part of the Library to a different drive, which you may wish to consider. You can change the location of the originals using the Lightroom Preferences>Local Storage tab.
