Is restore last known good configuration the same as restore a previous
registry?

LKGC are the system settings used when the OS last loaded successfully.
IF one restarts the system *more* than THREE times, then LKGC will no
longer be able to load.

'restore a previous registry' is *not* the same and can be any previous
backup of the registry; whether it actually loads the OS or not depends
on the integrity of the backed up registry.

Why do you ask ?

Does this mean if I boot normally three times in a row and then try to
boot using LKGC my system will not load?

Why is that?

Not exactly/quite.

Not sure what you mean by restore a previous registry.

If you mean System Restore, here is a friendly MS page:

No. If a system boots *normally* then LKGC is still intact. The boot 3
times limit only applies when a system does *not* boot normally.

The registry contains one CurrentControlSet and 2 backups of it.
LKCG relies on the CurrentControlSet to load the software and hardware
settings that were previously loaded successfully.
If the system can not boot normally using CurrentControlSet, using LKCG
will defer to CurrentControlSet001.
If no joy, then it will attempt to load the remaining CurrentControlSet.
Which adds up to 3 chances to use LKCG.

Hmmm. I don't think it quite works like that, either the LKGC works or
it doesn't. In it sleeping state there is no Current Control Set, this
set only exists on a successfully booted computer, after the computer
has booted and after a user has successfully logged on the now existing
successful Current Control Set is copied over to the Control Set to be
designated as the LKGC, this happens every time a user logs on
successfully to the machine.

The LKGC is identified in the HKEY_LOCAL_MACHINE\SYSTEM\Select key,
logging on to Safe-Mode will not reset the LKGC, the LKGC will only
change (be copied over) after a user normally logs on successfully to
the machine.
