I am not sure, I think that you may, but you can do it the "hard way" by converting the numbers using the following list:

SOURCE: Restore apps to TI-84 Plus
I am always happy to polish the apple...before I eat it. (Just joking!)
All the applications that were preloaded on your calculators are available to download freely from http://education.ti.com Use the tab Download--> Apps and software. Then select software for the TI83/TI84 Family. While you are at the site download the TI Connect, if you do not have it already. The link follows.
http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html You can also download the latest OS there. (Beware: while applications and programs are compatible with the TI83 and 84, the Operating systems are not.)
Install TI connect on your computer and run it to open the main Window.Then connect you calculator to a USB port and, in the TIConnect main window Click the TIDeviceInfo icon. Software will try to retrieve the info. If it does your calculator is ready to communicate with the computer.
If it tells you Device Not found , Click communication settings in same pop up window where it said Not found, and Select Device, Select Cable (USB or TIsilver cable), Select Port (USB1) and Click OK..
If you are lucky and it works, you can reinstall the OS, which can be downloaded from education.ti.com. You drag and drop the OS on the TIconnect main window. Calculator must of course be connected to computer. To install an application already downloaded to your computer, drag it to the main window of TI Connect and drop it. Keep installing, the appilcations you want.
If you have problem with TIconnect, use the calc-to-calc cable to transfer the Apps from a working calculator. You should be on Receive mode [2nd][Link] --->>Receive. (When both calculators are ready hit enter.) The other calculator must be set to Send [2nd][Link][SEND][C:Apps]. A list of Apps appears. Scroll down the list. If you want to transmit un app you press [ENTER] when the arrow reaches its line. Once an app is selected , a small square appears on the left. After the selection, Hit transmit. I suggest you transfer Apps, one after the other. Avoid selecting them all and send them all at one go.
If you want to transfer the OS of a working calculator the sending calculator must be on [2nd][Link][SEND][SendOS]. TI83Plus OS is not compatible with TI84Plus nor TI84PLUS Silver edition OS.
In addition to the preloaded applications, you can also transfer programs the same way. For a repository of TI83PLUS/TI84PLUS and TI84+ SE, go to www.ticalc.org (or com), visit the archive section of the site.
Hope it helps.

SOURCE: Change TI 84 OS to TI 89 OS??
And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.
