No, at least not what this verse is addressing:
Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
There will come a time when the gospel will be preached in all the world, then the end shall come. It's an endtimes, global happening which precedes the end which would be the end of this current age with a new age beginning. This likely is a reference to the testimony of the two witnesses and/or the testimony of the beheaded martyrs and the end being the second coming and the new age of the thousand years rod or iron rule over the nations.
Rev 11:7 And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.
Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
