Ooops, sorry, I haven't read carefully enough. The answer is no. At least the "series" command isn't doing that. Internally a series is stored (more or less) as the list of coefficients plus a function to extract "the next coefficient". Yes there is a function object, but there is no explicit expression like (-1)ˆn * x^(2n+1) / (2n+1)! stored internally.
