There was a similar question here: Losing at Spider Solitaire However, what I'm asking is different.
The game has a rule that it would not deal the next ten cards, unless there is already a card in everyone of the ten slots. What I'm asking is whether it is theoretically possible that at any time, except the last deal, there might be a situation with less then 10 cards on the table?

The initial deal in Spider is 54 cards. Cards can only be removed in runs of 13 (A-K). So it is theoretically possible for that initial deal to allow you to remove four full runs of cards and be left with only 2 cards on the board (13 * 4 = 52).
Here is one initial position where the cards are dealt almost in sequence that would create this scenario:
