No - you cannot choose to claim the days you are exempt from the substantial presence test under the F-1 visa class in order to file as a resident alien.
However, if you are a
Nonresident Alien who will become a Resident Alien under the Substantial
Presence test in the year following this taxable year, you may elect to be
treated as a Dual
Status Alien for this taxable year and a Resident Alien for the next
taxable year if you meet certain tests. Refer to the First Year Choice area,
under Dual-Status Aliens, of Chapter 1 in Publication 519,
U.S. Tax Guide for Aliens.
