Hi Peter,

As long as the Time Capsule drive doesn't die first; you are good.
Also I am assuming all the MacBooks are complete system backups (not just Users 
Home Directory).

Each computer has its own Sparse disk Image bundle (sparsebundle) on the backup 
drive.
So you can restore one without harming any of the others.

To answer your question:

No not at all.
Simply launch Migration Assistant, select your Time Machine backup and select 
which settings and users to copy. It doesn't care that your backup is a Snow 
Leopard backup.

For more information here is an article about how to use Migration Assistant in 
Snow Leopard. It is virtually the same in Lion.
