It is not recommended. If you W2 form is lost the employer can change your withholding to single with no deductions. The employee should be notified so an adjustment can be made. An employer that knows that an error is made may have to change something.

Withholding is the portion of an employee's wages that is not included in their paycheck but is instead remitted directly to the federal, state, or local tax authorities. Withholding reduces the amount of tax employees must pay when they submit their annual tax returns. For employees, withholding is the amount of federal income tax withheld from your paycheck.

The same amount is paid by the employer and the employee toward these two taxes. Only the employee pays their Federal, State, and/or Local Income tax withholding but the employer is responsible for withholding these taxes and remitting all of them to the IRS on a timely basis.
