I don't think the question is so clearly answered.

Can the 18F452 self-program?  YES

Like the 16F877? NO

The 16F877 could read/write/erase individual instruction memory locations.  The
18F452 can read one byte, write an eight byte block, and erase a 64 byte block.
There is also an errata that describes a data corruption condition that can
occur if interrupts happen during a table write.
