There isn't, if you use partitions. It could (would) go wrong if you tried to put an XFS filesystem, or md RAID with a v1.1 superblock, on a whole disc without a partition table *and* you tried to put a bootloader on. I can't say it's ever occurred to me to do that, because I always assumed that whatever I put in a partition used all of it, and I couldn't expect to double-book the beginning of it and have it work.
