Can you charge with a standard action gained by spending a mythic point?

[Aegys]

The core book says you can charge on a standard action if that's the only action you can take that turn, though you can only move your normal movement on this charge.
Once you reach tier 2 mythic you can spend a mythic point to take a free standard action.
I guess the real question is when does your normal turn brought on by the initiative order end, and your new standard action gained via spending a mythic point begin?
Are these separate turns? Can you use this mythic inspired standard to take a charge where you only move your normal movement?

I am not familiar with mythic, but you answered your own question. You can charge on a standard action if that's the only action you can take that turn. Gaining an extra standard action is not a bonus turn (unless it says so somewhere)
