No.
You can just ccd every piece of disk you can get your hands on together,
and then use the standard disklabel tools to create partitions at will;
removing partitions is also easy, and provided you have enough free
space after[1] a disk slice, growfs(8) works fine.
By the same thinking, enlarging a ccd can almost certainly be made to
work.
However, I can see why one would prefer full LVM. And none of the above
are likely to give any less than disastrous results if you don't unmount
the filesystems first.

[1] From my reading of growfs(8), I'm not quite sure it can extend
filesystems into space free before the filesystem. Of course, dd solves
this problem nicely.
Of course, dd'ing a disk of which you have no backups over itself is
asking for trouble.
