I think the second line is slightly problematic for white. Firstly instead of 7... exd5 black can improve with 7... cxd5, leading to an Exchange Slav where white has played e2-e3 before Bf4. I would already prefer black. Secondly, even if black plays 6... Qb6 it's not clear what white is hoping for. After 7. Nh4 black can exploit queen's premature excursion to b3 with 7... Qxb3 8. axb3 Bc2. I would also argue that 3. Nf3 dxc4 is something that white should welcome with open arms, not try to avoid. After 4. e3 b5 5. a4 e6 6. axb5 cxb5 7. b3 Bb4+ 8. Bd2 Bxd2+ 9. Nbxd2 a5 10. bxc4 b4 11. Ne5 (which I assume is the line that worries you based on your reference to the Noteboom) white has a significantly improved version of the Noteboom, having spent one tempo moving the bishop to d2 instead of three moving it to b2. After the mainline 11. Ne5 Nf6 (11... Bb7?? 12. c5! +-) 12. Be2 0-0 (12... Bb7? 13. Qa4+ +/-) 13. Bf3 black's development is not going nearly as smoothly as in the Noteboom, and I think white should be very happy with the outcome of the opening.
