Is there any function in MATLAB which convert the image type? If i rename the name of the image manually from "lena.bmp" to "lena.tif" than will it work?

The file type is not determined by the file extension (in fact on linux files are not even required to have a file extension). You cannot just change an image file format by changing its file extension. You need to use MATLAB or any reputable image viewer/editor to convert from one format to another.

Read the image in
I = imread(name.bmp);
h = imshow(I);
saveas(h,name,'tif');
In you case name is 'lena'. Hope this helps!

Or it would likely be much easier to simply use any reputable image viewer/editor, such as MS Paint, or Irfanview.

Use strrep (or fileparts), and imread() and imwrite(). Simply change the filename.
inputFileName = 'C:/whatever folder/lena.bmp'
outputFileName = strrep(inputFileName, '.bmp', '.tif')
theImage = imread(inputFileName);
imwrite(theImage, outputFileName);
