If you want to change file name of an already uploaded document try below code:

Get the uploaded file object using ID/ URL or which ever way suits you, then try this:

ListItem item = uploadedFile.ListItemAllFields;
item["Name"] = "NewName";
// use OverwriteCheckIn type to make sure not to create multiple versions 
uploadFile.CheckIn(string.Empty, CheckinType.OverwriteCheckIn);

If you want to change file name of the file while uploading try below code:

 using (FileStream fs = new FileStream(filePath, FileMode.Open))
    FileCreationInformation newFile = new FileCreationInformation();
    newFile.ContentStream = fs;
    newFile.Url = newFileName;
    newFile.Overwrite = true;
    List docs = web.Lists.GetByTitle(“Shared Documents”);
    Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
