Why the odd ball capacitor (22uf non polarized) for C19?

Schematic indicates to look at AVR040 Application note. The application note does not use a 22uf capacitor on the reset line.

I'm guessing the large value is used here to prevent false resets in the electrically noisy automotive environment?

Can't a polarized capacitor be substituted here? Like a 22uf tantalum?
