I've viewed LZ-DOS in memory and compared it to MS-DOS 7.10. Almost everything is identical, so yes, it is 100% compatible, since it's a ripped copy of MS-DOS 7.10 with some copyright information removed.

Not all the copyright information is removed, though - it still contains this in memory:

"MS-DOS Version 7 (C)Copyright 1981-1995 Microsoft Corp Licensed Material - Property of Microsoft All rights reserved"

It's bad enough to be copying other people's software when they don't want you to, but to be removing credit? That's pretty low.
