Well, literally, the answer to your question is "Yes." You certainly can file an income tax return using partial information, then amend that income tax return when you get more information, then amend - maybe again and again - as information trickles in. But why would you? You are creating an incredible amount of work for yourself - having to amend and amend - and you risk the possibility of getting the IRS confused - which will certainly work to your disadvantage - and getting yourself confused as well, maybe showing a refund with the first filing, then having to pay taxes with the second filing, or third, or fourth.
I strongly recommend that you not get yourself in a lather trying to get a refund at the earliest possible second. If you and/or the IRS get confused you could find yourself in a protracted struggle with the IRS trying to get things straightened out. When you have all your information, file your income tax return.
