I am afraid that he may simply call any online writings fanfiction, and his question is one asking if he can write something in story format versus timeline format, for which case he can.

Or, perhaps he means writing story-format articles based on timelines, for which case he can as long as he owns the timeline or has permission of the owner.

The final potential definition of his is writing something based on an existing work, in which case the answer is a definate no.
