No. A qualified charitable distribution (QCD) can only be made from IRAs. Money in employer-sponsored retirement plans such as 401(k)s and 403(b)s is not eligible for QCDs.
Per IRA FAQs - Distributions (Withdrawals), "Generally, a qualified charitable distribution is an otherwise taxable distribution from an IRA (other than an ongoing SEP or SIMPLE IRA) owned by an individual who is age 70½ or over that is paid directly from the IRA to a qualified charity. See Pub. 590-B, Distributions from Individual Retirement Arrangements (IRAs)) for additional information."
