If I missed a W-2 on my 2017 return could I use it this year?

Do you mean 2016?

Absolutely not.  If you forgot to enter a W-2 on your 2016 tax return you have to amend that tax return to include it.  You cannot use it on your 2017 tax return.

If you need to enter additional information, delete something, or change something on the the tax return you already filed, you have to wait until your return has been fully processed, then you can prepare an amended return, called a 1040X.  You cannot e-file a 1040X.  It must be printed, signed and mailed to the IRS.

 After you print, sign and mail your amended return—1040X— to the IRS wait about 3 weeks and then you can begin checking on it at the IRS website.  Be aware that it can take at least 3-4 months for an amended return to be fully processed (or sometimes even longer.)
