I think the only limit is 16TB max file system, so off hand I'd say no. But this also applies to ext4.

I just tested with 3.13.4-200.fc20.i686+PAE.

XFS (sdc): file system too large to be mounted on this system.
EXT4-fs (sdc): filesystem too large to mount safely on this system.

The same 32-bit kernel mounts a 20TB Btrfs volume with no complaints, so I don't know its limit.

XFS mounts with inode64 by default, same as x86_64. So that's good.
